储能是可再生能源大比例使用的关键支撑技术,储能可为可再生能源的接入和利用提供平滑输出、削峰填谷,将间歇式能源转变为友好电源。“据中关村储能产业技术联盟项目库不完全统计,截至2014年底,全球应用在电力系统的储能项目(不含抽水蓄能、压缩空气及储热)累计装机规模为845.3兆瓦,2014年新增装机111.6兆瓦,年增长率15%,较上年增幅提升2个百分点。其中,中国储能累计装机规模达84.4兆瓦,占全球储能装机的10%。”在日
Energy storage is a key support technology for large-scale use of renewable energy sources. Energy storage provides smooth output, access to and utilization of renewable energy sources, peak load shifting, and the conversion of intermittent energy sources to friendly power sources. According to the incomplete statistics of Zhongguancun Energy Storage Technology Alliance project library, as of the end of 2014, the cumulative installed capacity of energy storage projects (excluding pumped storage, compressed air and heat storage) used in the power system in the world was 845.3 MW, 2014 The new installed capacity of 111.6 megawatts, an annual growth rate of 15%, an increase of 2 percentage points increase over the previous year, of which China’s cumulative installed capacity of 84.4 megawatts, accounting for 10% of global energy storage installed capacity.
